| description | In recent years, due to the disadvantages of poor overall performance and low safety reserve, there are more and more reinforcement cases for the bridge deck system of long-span arch bridges under the stress of beams. In order to give full play to the effect of adding large longitudinal beam method to strengthen the bridge deck system of long-span arch bridge and improve its stability and seismic performance.Based on the endurance time method (ETM) and the park-ang damage model, a theory for determining the suitable reinforcement section of long-span arch bridge deck system is proposed considering the seismic performance requirements and stability characteristics. Taking a typical flying swallow type CFST Tied Arch Bridge as an example, yield seismic time of three kinds of large longitudinal beams with common sections is compared by numerical simulation. It was indicated by the results that: 1. The bridges strengthened with three types of longitudinal beam sections meet the requirements of structural strength, stiffness and overall stability. It is suggested to adopt box section, which can improve the static and dynamic performance. 2. For the bridge reinforced with three types of large longitudinal beams, the dead load state such as arch axis figure and springing compressive stress has little change. 3. The method for stability and seismic performance evaluation of long-span arch bridge deck system after strengthening of girder can complete scheme selection effectively. The cyclic pushover method with ISO loading protocol was recommended as the most suitable method. |
